Teeth Whitening

3 Types of Teeth Stains

  1. Extrinsic Teeth Stains: These are surface stains, most commonly caused by smoking, coffee, tea and wine.
  2. Intrinsic Teeth Stains: These are internal stains, most commonly caused by an over exposure to fluoride at an early age or trauma in an adult tooth.
  3. Age-Related Teeth discolouration. This could be both extrinsic and intrinsic factors. The enamel that covers the teeth do get thinner over time from abrasion such as tooth brushing, which allows the dentin to show through. Extrinsic factors such as smoking and excessive consumption of acidic food could result in staining, and intrinsic factors such as chips or injuries to the teeth could result in the discolouration of the teeth.

How to whiten the teeth

Regular Cleaning:

Most surface stains can be removed with just a simple dental cleaning with your dentist, however, more stubborn stains are unable to be removed.


You may look into doing resin laminates or Porcelain Veneers to change the colour and mask deeper stanis.


Teeth Whitening (Bleaching):

Teeth Whitening is good when your teeth have a lot of enamel and are not stained.

It will enhance the colour of your natural teeth; However, it will not remove existing stains, and may even result is a greater colour difference.


The only added ingredient in Dental Whitening is Hydrogen Peroxide. Due to regulations, only approved dental practices are allowed to use teeth whitening products with a concentration more than 0.1% of Hydrogen Peroxide.


Check with your dentist to see whether you are suitable for bleaching.
